I had to sort by `rank` instead of `rank desc` - need to double-check that:

```sql
with original as (
    select

select
    original.*,
    [global-power-plants_fts].rank as rank

The equivalent using `rank_bm25()` for FTS4 would be:
```sql
with original as (
    select

        *
    from [global-power-plants]
